TECHNICAL FIELD

The present disclosure relates to self-serve food locker assemblies, systems, and methods. More particularly, this disclosure includes automated self-serve food locker assemblies, systems, and methods providing touchless operation of pass-through food lockers.

BACKGROUND

As consumers demand more diverse food options without sacrificing quality and convenience, restaurants and fast-casual brands are seeking innovative ways to provide a unique and positive customer experience. Many brands emphasize speed and ease of ordering by offering to-go menus and the ability to order food online. When managed effectively, this minimizes the wait time for customers while providing the restaurant with an additional revenue stream. However, unique challenges are presented when attempting to create a seamless takeout ordering experience.

A typical restaurant relies on the availability of staff members for handling customer to go orders. In a busy restaurant setting, this can be a stressful and time-consuming ordeal for both the customer and the restaurant. Mix-ups and unnecessarily long wait times are not uncommon. Human labor is one of the highest operational costs for restaurants; however, people are becoming unnecessary, and even detrimental in many scenarios, such as handling of take-out orders.

Another challenge associated restaurants face in providing takeout is combating heat gain or loss in the food while awaiting pickup. Takeout orders are often placed in paper or plastic bags, which do little to prevent heat gain or loss during storage. Receiving food too hot or cold often frustrates consumers can damage a restaurant's reputation. In addition, perishable foods cause safety concerns when mishandled. The USDA recommends that once food is cooked, it should be stored at 140 degrees Fahrenheit (60 degrees Celsius) or above, and cold foods should be stored at 40 degrees Fahrenheit (4.44 degrees Celsius) or below until consumed. For takeout foods, it is recommended that perishable foods should not be kept between 40 degrees Fahrenheit (4.44 degrees Celsius) and 140 degrees Fahrenheit (60 degrees Celsius) for over two hours.

The Covid-19 pandemic heightened the need for takeout food delivery improvements within new health safety protocols. Minimizing human touching of prepared takeout food containers and delivery compartments is a demonstrable factor in limiting global bacteriological and viral contaminations.

There is a need for food locker assemblies, systems, and methods that provide: 1) automated control of food locker access for loading and unloading the locker; 2) touchless pass-through food compartments for active food modular locker arrays between a kitchen environment and a public space; 3) ultra-violet sterilizing lights in germ food lockers; 4) separate hot-cold lockers with integrated timed heating/cooling temperature control; 5) food compartment doors with integrated human machine interface (HMI) control screens; and 6) linear drive hardware on touchless food compartment motorized doors.

SUMMARY

The disclosure details a unique steel cabinetry series that leverages today's technology to eliminate the common challenges involved in takeout ordering. The to go ONDO™ Self-serve Food Locker assembly, system, and method with hot and cold food storage capability provides a convenient automated self-service ordering platform for a virtually enhanced dining experience. Not only does the system benefit consumers by allowing them to skip the lines and retrieve their orders directly, but it also reduces the restaurant's operational costs by eliminating the need for additional staff. Through automating the ordering process and eliminating unnecessary staff intervention, restaurants can reduce congestion in waiting areas as multiple customers are served simultaneously. The customer will experience streamlined service with assurance they are receiving their food at a safe temperature and from a bacteria and virus free storage environment.

The principal components of the ONDO™ Self-serve Food Locker assembly, system, and method are food locker doors with an integrated Human User Machine Interface, (HMI) or User Interface (UI), which serve as a customer interface. The doors are housed in cabinetry and provide pass-through access using automated flip-up food locker doors or conventional opening food locker doors for easy order retrieval. Integrated heating and/or refrigeration system control food locker internal temperature for preserving the customer's order. The ONDO™Self-serve Food Locker assembly, system, and method provide a “modular,” energy efficient insulated system utilizing parallel stacking of self-contained towers for expansion as befits venue or facility space availability.

Once the customer places an order via smartphone or through a touch-screen kiosk in the restaurant, they will be prompted for payment, which can be done at the kiosk or via smartphone for mobile orders. Once payment is received, the prepared food is placed in an ONDO™ food locker and the kiosk or mobile application notifies the customer that their order is ready for pickup. The notification indicates the food locker number where the order is placed and a reminder it must be picked up within a predetermined time frame. The customer has this window of time to retrieve their food from the food locker before the food is removed and discarded by restaurant staff. The food locker's HMI/UI screen displays the locker number, the customer's first name or other customer provided data for easy identification. In addition, the countdown from the predetermined pickup time window is displayed. Once the customer finds the correct locker, he or she is prompted to press an on-screen button for input of a PIN number or a bar code or quick response (QR) code to open the food locker. This customer input prompts the automated food locker doors to open, allowing food retrieval. An integrated occupancy sensor will sense when the food has been collected and will automatically close the door.

The ONDO™ Self-serve Food Locker assembly, system, and method also incorporate monitor screens for both the food service attendant(s) and kitchen staff. This capability provides monitoring each order's queue and status.

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS

Embodiment of the ONDO™ Self-serve Food Locker assembly, system, and method are disclosed in FIGS. 1-24.

FIG. 1 depicts a representative 3×4 array of modular automatic pass-through self-serve food lockers 12 for an embodiment of the ONDO™ Self-serve Food Locker assembly, system, and method. The main cabinet houses twelve individual modular automatic pass-through self-serve food lockers 10 with internal dimensions of 12″×12″×19″ (30.48 cm×30.48 cm×48.26 cm). Each food locker 10 is configured for hot or cold food item storage. Multiple modular arrays 12, size permutations, and combinations of the disclosed food lockers 10 for variants are in depicted in FIGS. 3A-6D. Food service staff can toggle between heating and refrigeration according to the food being prepared. Each individual food locker can be configured for heating or cooling with the flip of a switch. Customer and administrative access to the food locker ordering, retrieval and other delivery for some variants is managed through an integral or remote touch screen 96, FIGS. 1, 2, 19A and 19B. Operational control of the food locker, including the temperature is managed through key board and touch screen input, FIGS. 11A, 11B, and 13, to a digital processor, a memory module coupled to the digital processor, a network interface comprising wireless connectivity and coupled to the digital processor, and software, via a web portal, mobile applications, or on-site digital control station FIGS. 7-15, 19A and 19B. Through this combined technology, a variety of functions can be implemented to manage the food lockers 318, FIG. 8, including temperature control, such as automatic temperature conversions based on time of day, via temperature readings from embedded probes (if the temperature reaches a rating out of the threshold, the compressor or heating pad will automatically energize to bring that temperature back to the desired rating), or via a queuing system (an algorithm that dynamically assesses the state of all lockers and orders to automatically convert temperatures in real time, as needed). The system for embodiments of the ONDO™ Self-serve Food Locker recognizes orders and assess locker availability based on temperatures and the required temperature for an order, 318, FIG. 8. If there are no available lockers for the needed temperature, the system automatically converts a vacant locker to the desired temperature while the kitchen is preparing the meal, 316, FIG. 8,

Embodiments of the ONDO™ Self-serve Food Locker assembly, system, and method provide electrical connectivity as depicted generally in the representative electrical schematic diagram 200, FIG. 7. 12 VDC power supplies 202 and 204 provide electrical power to the microprocessor 206, user interface touch screen 296, bar code or quick response code scanner(s) 298, and locker control circuitry 208 for the solenoid lock, linear actuator, LED lighting, evaporative plate, and service resource module(s) of the food locker 210.

Embodiments of the ONDO™ Self-serve Food Locker assembly, system, and method of the layout can apply to individual food lockers, modular arrays of food lockers, or the entire modular array wall of food lockers, FIGS. 3A-6D. For example, if a wall has 3 columns of 4 boxes, the system operator can set columns 1 and 2 to hot, and column 3 to cold (cluster method); likewise, the system operator could set the first 2 boxes in column 1 to hot, the bottom 2 boxes in column 1 to cold, and the remaining 2 columns to ambient (combination of individual and cluster). This locker management 318 can be set up in the system for any combination or number of modular arrays of food lockers, FIG. 8.

Embodiments of the ONDO™ Self-serve Food Locker assembly, system, and method provide multiple-size, dual-zone food lockers where two lockers are set adjacent with an insulated divider separating them. These dual-zone lockers share one forward and one rear door which would unlock for placement/retrieval in/from both lockers. This gives system operators the option to offer multiple meals for one order. For example, if a soda and hamburger were ordered, one locker would be set to hot and the other to cold; if after that, someone orders four hamburgers, the system operator could set both lockers to hot, to place two hamburgers in one locker and two hamburgers in the other. This flexibility for various orders with multiple foods selected highlights the novel utility of the ONDO™ Self-serve Food Locker assembly, system, and method. This utility offers the flexibility to accommodate for additional space during peak periods. Both dual-zone lockers need not be filled. If the single-zone lockers are all occupied, and the system operator needs to place an additional order, they can simply use the dual-zone locker for a single item.

Embodiments of the ONDO™ Self-serve Food Locker assembly, system, and method provide lockers constructed of a food grade stainless-steel cabinet frame cored with flame retardant material. The locker interior is lined with 2400-degree Fahrenheit heat retardant thermal insulation. A thermal break 66 is installed at each door opening to limit condensation, FIGS. 16A-17B. Mounted on the cabinet of lockers are doors comprised of dual paned insulated glass fixed within a composite frame that houses a human machine interface with LCD screen to serve as a customer interface. The locker doors are tempered insulated glass with UV blocking film 70 fixed within a composite frame for users to see the food, and internal LED lighting. These locker doors can also be solid, matching the finish of the unit. The front and rear locker doors are mounted to the cabinet via a linear drive, allowing the doors to automatically open and close when prompted. Some embodiments of the ONDO™ Self-serve Food Locker assembly, system, and method provide traditional spring-loaded swing doors without screens are also illustrated as part of the design as a feature set. Some embodiments of the ONDO™ Self-serve Food Locker assembly, system, and method provide manual rear doors mounted to the rear of the locker for loading prepared orders awaiting customer pickup, FIGS. 20-24. Food grade stainless steel left and right-side panels, 122 and 120 respectively, and base 124 house variants of modular food locker configurations, FIG. 24.

Embodiments of the ONDO™ Self-serve Food Locker assembly provide a safety light curtain sensor transmitter 40 and a safety light curtain sensor receiver 42 on opposite sides of an automatic touchless user access door providing dual panel insulated glass with UV blocking film 70 and access to a food grade stainless steel food locker cavity 72, FIGS. 16A-17B. The automatic touchless user access door is attached to and driven by a motorized linear actuator 48 affixed to a food locker external surface by an adjustable field serviceable linear actuator mounting assembly 58 and a linear actuator tension/compression assembly 56 with an electro-mechanical solenoid lock 50. The motorized linear actuator electronic control, driver, food compartment lighting, food compartment UV lighting, and access door safety interlock are all controlled by a front flag food locker chamber control module 44.

The food locker access door status is visibly displayed by an access door opening indicator lamp/LED 52. An automatic or manual (not depicted) food locker kitchen access door is controlled by RFID sensor or fingerprint sensor 62, FIGS. 16A-17B. An ultra-high-molecular-weight (UHMW) high-heat polyethylene thermal break 66 frames the access food locker door contact with the opening to the food locker cavity.

The kitchen access door driver, food compartment lighting, food compartment UV lighting, and access door safety interlock are controlled by a rear flag food locker chamber control module 46 and an electro-mechanical solenoid lock 50. A santoprene, dart-style high temperature polyvinyl chloride gasket 64 insulates the customer access door and kitchen access door to the food locker cavity. Heating the food locker cavity is achieved by a silicone rubber mat heating element with a heat diffuser/conductive aluminum plate 54.

Cooling the serf-serve food locker cavity is achieved by a refrigerant line feed 76 from a food locker module centric compressor 108, a capillary tube refrigerant return line 78 to the compressor 108, and a coolant control solenoid valve 74, FIGS. 16A-17B, 23. The food locker cavity is insulated by 2 inches thickness of closed-cell polyiso-foam with embossed aluminum faces 68 enclosed between inner and outer food locker cavity shells 68. An external food locker top surface provides a wiring access point 60 for food locker cavity internal lighting. A main power source drawer 90, FIG. 18, with a Programmable Logic Controller (PLC) supplies signal distribution for customer door access and power distribution for alternating current, direct current and emergency battery power for the system. The power source drawer 90 also has provisions for an on/off circuit breaker with an integrated power switch 92 and a switch position for chamber emergency access 94.

Technology stations provide convenient housing for the User Interface Touch Screen PC. One version consists of a food grade stainless steel or powder coated finish 100 towers 102, FIG. 19A that can be attached to self-contained stackable food locker columns with independently controlled pass-through food lockers and mechanical/electrical access doors with integrated handles and security lock, i.e., FIGS. 1, 20-24. The second version of technology stations is a housing that can be hung or attached to a column or wall with a food grade stainless steel or powder coated finish 100, FIG. 19B. A typical food locker column consists of a locker as described in FIGS. 20-24 providing temperature-controlled food locker chambers, FIGS. 16A-17B, the main AC power source w/PLC interface and DC power drawer 110, the pressure controlled compressed gas refrigeration system 108, all contained within the tower. FIGS. 3A-6D, and 20-24 demonstrate several of the modular configurations for the embodiments of the ONDO™ Self-serve Food Locker assembly, system, and method components disclosed and described in FIGS. 16A-19.

Embodiments of the ONDO™ Self-serve Food Locker assembly, system, and method provide lockers in a variety of configurations to suit a wide range of food and beverage items.

Hot food lockers are provided for cooked foods served hot. The hot configuration includes an induction warmer within the food locker interior.

Cold food lockers are provided for preserving drinks, frozen foods, salads, or other foods served cold. The cold food locker configuration includes an evaporative plate that lines the food locker interior.

Hot and Cold Combination food lockers provide an interior partitioned into two sections. One section provides the silicone mat heater, and the other provides an evaporative plate lining for storing both hot and cold foods at the appropriate temperature. Hot and cold lockers are electronically controlled via digital control mechanisms and sensors. Individual lockers can be connected to heating or cooling via a time delay relay activated switch at the rear of the unit. Lockers storing hot food include a silicone rubber mat (SRM) heater 54, FIG. 16A, with adjustable heat settings for keeping food at an optimal temperature while awaiting pickup. The warmer also includes built-in safety features such as over-heat protection to mitigate burn and fire risks.

Glass Door with Integrated HMI LCD Screen

Food locker access doors are constructed of a glass panel mechanically fastened to a composite frame. Each food locker includes an integrated human machine interface (HMI) panel mounted to the door frame behind the glass. The HMI is programmed so graphics and textual information, such as food locker number and the first name and last initial of the customer are displayed on the screen. The HMI is linked to the kiosk within the restaurant, which is a platform for ordering and processing payments. The food ordering and payment program enables the customer to open the food locker door by pressing an on-screen door open button when prompted. After the food is removed, an integrated occupancy sensor signals the automated doors to close after a predetermined time.

Automated Flip-Up Doors

Embodiments of the ONDO™ Self-serve Food Locker assembly, system, and method provide an automated system activating linear drive hardware, which allows the food locker doors to automatically open when prompted by the customer. The automatic food locker doors allow for a streamlined and elegant, handle-less cabinet design. The sleek design simplifies cleaning while giving an aesthetically pleasing appearance. With this system, the food locker door silently glides up and out of the customer's way, which provides touchless, and unobstructed access to the particular modular food locker housed in the cabinet.

Automatic food locker door mounting hardware is mechanically fastened to the composite frame and the lift mechanisms are fastened on either side of the food locker's interior cavity FIGS. 16A-17B. Once the door mounting hardware is mounted to both the food locker door frame and the food locker interior, the food locker door is easily removed and swapped if needed without tools.

The linear drive hardware 48, 50, 56, and 58 to activate the automatic food locker doors are powered via a 12V power supply mounted in a field serviceable drawer in the bottom of the cabinet and external to each individual modular food locker in the array of food lockers in the cabinet, FIGS. 16A-18. The linear drive hardware connects a push button switch, so that the customer can close the food locker door with the push of an on-screen button. The food locker door can also be programmed via the HMI to close automatically after a predetermined time. The linear drive hardware 48, 50, 56, and 58 also establish a wired connection to a push button battery backup switch allowing the vendor to open the food locker should a power failure occur.

Integrated Refrigeration and Heating Systems

Hot and cold food lockers are electronically controlled via digital control mechanisms and sensors. Individual food lockers can be connected to heating or cooling via a time delay relay activated switch at the rear of the unit. Food lockers storing hot food contain a 110V silicone mat heater 54 with adjustable heat settings for keeping food at an optimal temperature while awaiting pickup FIGS. 16A-17B. The warmer also includes built-in safety features such as over-heat protection to mitigate burn and fire risks.

Variants include food lockers configurated for cold food and beverage items, refrigerated with an evaporative plate lining the internal food locker cabinet space. Using a plate type evaporator 80 allows for a compact, cleanable surface on the interior of the food locker. The evaporative plate 80 has an integrated supply and return for circulating refrigerant throughout its entire surface area. This supply and return will be piped to a compressor and evaporator, which can either be remote to the unit, or housed within the lower portion of the cabinet. The plate is a light weight, formable metal such as aluminum, formed to line the interior walls of the food locker.

Hot and Cold food lockers are partitioned to integrate both the silicone mat heater 54 and the evaporative plate 80 for storing hot and cold food items, respectively.

FIG. 15 is a flow diagram illustrating a method of runner use 500 for embodiments of an ONDO™ Self-serve Food Locker assembly, system, and method under the disclosure. This method 500 may be performed by processing logic that comprises hardware (e.g., circuitry, dedicated logic, programmable logic, microcode, etc.), software (e.g., instructions run on a processing device to perform hardware simulation), or a combination thereof, and provides the operational steps for the apparatus and system.

The system generates a unique code associated to each customer's individual order. This code will be sent to the customer (via SMS, email, mobile app, etc.) upon completion of their order, FIGS. 8-13B. All the system access and control information are stored on the cloud database, and available to view on the ONDO™ web portal.

A customer places order through any means (mobile app, 700, 702, FIGS. 19A and 19B, kiosk, FIG. 19B, at register, on website) 504, FIG. 14. Once the kitchen has prepared the order, the runner approaches the ONDO™ wall. In some capacity, the runner is identified by the system as a runner (specific user privileges). This can be through facial recognition, employee badge, PIN code, etc. 552, FIG. 15. The runner profiles are created by the administrator or upon initial implementation to provide the appropriate users “runner” privileges. The system reads their code and cross-references with the database for identification of the user, along with information; specifically, their user privileges.

The system indicates which locker(s) to load with food. This can be done through these ways: The runner scans a 2D or 3D barcode, and the system assigns a food locker based on availability, 316, FIG. 8. The runner manually indicates the temperature of each order through a user interface, FIGS. 11a , 11B, and 13, and the system assigns lockers based 316, FIG. 8, on availability and temperature of each locker. The temperature information is embedded in the 2D or 3D code, and the system reads that information to assign lockers based on temperature and availability.

The runner logs into the system using a mobile digital device 700 (wirelessly connected 720), FIGS. 19A and 19B, or stationary (touchscreen) user interface, FIG. 11A, after which the system identifies the user as a “runner” and logs them in with special user privileges, FIGS. 10 and 15. The runner is shown the state of all food lockers (available, occupied, hot, cold, etc.) 376, 402. From that, the runner decides which food lockers to load 404. Those food lockers are recorded in the system 406 with the associated orders and are now deemed occupied. The runner manually indicates the temperature of each order, and the system assigns food lockers based on availability and temperature of each food locker. The runner types in a code corresponding to the order number, in which the order information is embedded. The system reads that information to assign lockers based on temperature and availability. The system automatically taps into the database to update that food locker's state.

The food locker door is closed either automatically (after a set duration following food locker door unlock, through occupancy sensor which indicates food has been loaded and the runner's hand is not in the food locker any longer or through a combination of both) or manually.

The local system synchronizes with the cloud portal and stores information upon completion of loading, FIG. 8. That information includes, but is not limited to, time/date, order number, food details (if applicable), and status of food locker.

The cloud system sends a notification to the customer through one, or a variety, of: SMS text, Email, and/or mobile application.

Included in the notification are: 2D/3D barcode, unlock PIN, assigned food locker(s) number(s), ONDO™ modular food wall location (if the system is handling multiple locations), order information, a duration for pickup 410, 524.

Optionally, the system can generate subsequent notifications serving as reminders to the customer to pick up their order, and the time remaining before the possibility of pick-up has expired. If the food is picked up before expiration 542, the locker is set to available and any customer access codes for that locker are erased, 546. If the time has expired before the food has been picked up 534, the kitchen is notified to empty the locker and any customer codes for that locker are deactivated 536.

If the food is picked up before expiration, the customer arrives at the station and unlocks their assigned food locker(s) via the process selected by the customer namely, 2D/3D barcode, unlock PIN 538 or an unlock button on customer's mobile digital device 700.

The system reads the unlock code and cross-references with the data stored on the system microprocessor(s) and cloud-based data storage 390, 542, 560 as part of a digital processor, a memory module coupled to the digital processor and a network interface comprising wireless connectivity and coupled to the digital processor. A query is run in the local database that searches for the unique unlock code. If the unlock code is not found in the database, the user is notified that their code was invalid. If it is found in the database, the associated food locker door is unlocked. The system pulls all information regarding that order (the immediately relevant piece of information being the door identification number) 540 and signals the central relay controller to de-energize the magnetic lock for that respective food locker door for a set duration to give the customer an opportunity to approach the door and open it. The customer then retrieves their food from the identified food locker 542.

If the food is not picked up before expiration, the runner/administrator is notified of expired order(s) 536. The runner goes to the station and unlocks the food locker(s) with expired food in them and removes the food 548.

The food locker lock will remain de-energized for a set period, 380, FIG. 10. After that period of time, it will re-energize, then locking it. The unlock code remains active for a set duration after that, allowing the user to re-enter it if they missed the window of time the food locker door was unlocked.

The food locker status is then updated in the local database as “vacant/available”. Every time there is a state change in any food locker, such as this, the local microprocessor controller synchronizes the food locker status change with the cloud e.g., FIG. 14, 532, 528, 546.

The food locker door is closed either automatically (after a set duration following the initial unlock; or through occupancy sensors which indicate food has been loaded and the runner's hand is not in the food locker any longer; or through a combination of both), or manually. A timer can be set to trigger a notification to the administrator if the door is left open and automatically close the food locker door via linear drive. The relay board signals the specific linear driver to initiate door closing. A resistance sensor is implemented to deactivate door closing upon recognizing resistance to the door (example—If somebody's hand is still in the threshold) to prevent injury or malfunction. If this occurs, the system implements a secondary duration threshold where the food locker door is reopened for a set amount of time, and then it will attempt to close again. This can repeat a set number of times until a notification error message is sent to the administrator and the web portal. The administrator can deactivate that food locker for further use until reactivated. In a deactivation period, the food is considered unavailable for loading by the system so that no orders are routed to that locker. The deactivated food locker temperature control is turned off to avoid unnecessary power consumption. The administrator's food locker deactivation rights are discretionary.

To manually close a food locker door, the administrator and runners are notified of the open food locker door so it can be manually closed. An LED light 52 will default to alarm status and blink to indicate the food locker door has been left open, FIGS. 16A-17B. An error message on the digital control screen appears with the error message “Door ‘NN’ has been left open. Please close.”

The local system microprocessor controller synchronizes with the cloud portal and stores information upon completion of removal. That information includes, but is not limited to time/date, order number, food locker details (if applicable), and/or “food locker now available.”

In the descriptions above and in the claims, phrases such as “at least one of” or “one or more of” may occur followed by a conjunctive list of elements or features. The term “and/or” may also occur in a list of two or more elements or features. Unless otherwise implicitly or explicitly contradicted by the context in which it is used, such a phrase is intended to mean the listed elements or features individually, or the recited elements or features combined with the other recited elements or features. For example, the phrases “at least one of A and B;” “one or more of A and B;” and “A and/or B” are each intended to mean “A alone, B alone, or A and B together.” A similar interpretation is also intended for lists including three or more items. For example, the phrases “at least one of A, B, and C;” “one or more of A, B, and C;” and “A, B, and/or C” are each intended to mean “A alone, B alone, C alone, A and B together, A and C together, B and C together, or A and B and C together.” In addition, use of the term “based on,” above and in the claims is intended to include, “based at least in part on,” such that an un-recited feature or element is also permissible.
